Welcome to this Mometrix video about the immune system.<\/p>\n<p>Think of the immune system as the body\u2019s gladiator. It fights for us, defends us, and protects us. The immune system fights off pathogens, the viruses and bacteria that seek to invade our body. It defends us by sending out armies of disease-fighting <a class=\"ylist\" href=\"https:\/\/www.mometrix.com\/academy\/cell-function\/\">cells<\/a> when it senses an intrusion. And the immune system protects us in natural and artificial ways.  <\/p>\n<p>Let\u2019s take a look at how the immune system works, all in an effort to help us stay healthy.<\/p>\n<h2><span id=\"The_Lymphatic_System\" class=\"m-toc-anchor\"><\/span>The Lymphatic System<\/h2>\n<p>\nThe lymphatic system fights infections and keeps the body\u2019s fluid levels balanced. It protects the body from bacteria, viruses, and other pathogens. The lymphatic system has a number of important components, and we\u2019re going to take a look at five of them more in-depth.<\/p>\n<h3><span id=\"Lymph\" class=\"m-toc-anchor\"><\/span>Lymph<\/h3>\n<p>\nLet\u2019s talk about lymph. Lymph contains white <a class=\"ylist\" href=\"https:\/\/www.mometrix.com\/academy\/heart-blood-flow\/\">blood<\/a> cells that help fight infection. How exactly does lymph circulate? Lymph moves through our system to lymphatic ducts when the skeletal muscles contract. <\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.mometrix.com\/academy\/wp-content\/uploads\/2021\/10\/Lymphatic-Duct.png\" alt=\"A diagram of the human body with the lymphatic duct labeled on the left side near the shoulder\" width=\"549.9888\" height=\"367.2744\" class=\"aligncenter size-full wp-image-95221\" style=\"box-shadow: 1.5px 1.5px 3px grey\" srcset=\"https:\/\/www.mometrix.com\/academy\/wp-content\/uploads\/2021\/10\/Lymphatic-Duct.png 894w, https:\/\/www.mometrix.com\/academy\/wp-content\/uploads\/2021\/10\/Lymphatic-Duct-300x200.png 300w, https:\/\/www.mometrix.com\/academy\/wp-content\/uploads\/2021\/10\/Lymphatic-Duct-768x513.png 768w\" sizes=\"(max-width: 894px) 100vw, 894px\" \/><\/p>\n<p>Lymph only moves in one direction, unlike blood, which circulates through the entire body. <\/p>\n<h3><span id=\"Lymph_Nodes\" class=\"m-toc-anchor\"><\/span>Lymph Nodes<\/h3>\n<p>\nThere\u2019s a relationship between lymph and lymph nodes. Lymph nodes filter out harmful substances, ensuring clean lymph gets placed back in the blood supply via the subclavian veins in the neck.  <\/p>\n<p>There are lots of lymph nodes in the human body, as many as 700 of them, and they\u2019re located in the neck, armpit, and groin. <\/p>\n<h3><span id=\"Lymph_Capillaries_and_Vessels\" class=\"m-toc-anchor\"><\/span>Lymph Capillaries and Vessels<\/h3>\n<p>\nLymph capillaries pick up lymph fluid that leaks from our bloodstream and into tissue before returning that lymph to the circulatory system. Lymph vessels carry lymph throughout the body.<\/p>\n<p>Now we know about these lymphatic systems: the lymph, the lymph capillaries, lymph vessels, and lymph nodes. But what about the lymph tissue?<\/p>\n<h2><span id=\"Lymph_Tissues\" class=\"m-toc-anchor\"><\/span>Lymph Tissues <\/h2>\n<p>\nThe lymph tissues, which are rich in small white blood cells called lymphocytes, protect the body from bacteria and other pathogens. The tonsils, adenoids, thymus, spleen, and Peyer\u2019s Patches are all lymph tissues.<\/p>\n<h3><span id=\"Tonsils\" class=\"m-toc-anchor\"><\/span>Tonsils<\/h3>\n<p>\nTonsils, located in the pharynx, filter out pathogens that can enter through the mouth or throat. <\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.mometrix.com\/academy\/wp-content\/uploads\/2021\/10\/Tonsils.png\" alt=\"&quot;The tonsils are labeled on an illustration of a human head &quot;\" width=\"550.02\" height=\"307.05\" class=\"aligncenter size-full wp-image-95224\" style=\"box-shadow: 1.5px 1.5px 3px grey\" srcset=\"https:\/\/www.mometrix.com\/academy\/wp-content\/uploads\/2021\/10\/Tonsils.png 824w, https:\/\/www.mometrix.com\/academy\/wp-content\/uploads\/2021\/10\/Tonsils-300x167.png 300w, https:\/\/www.mometrix.com\/academy\/wp-content\/uploads\/2021\/10\/Tonsils-768x429.png 768w\" sizes=\"(max-width: 824px) 100vw, 824px\" \/><br \/>\n&nbsp;<\/p>\n<h3><span id=\"Thymus\" class=\"m-toc-anchor\"><\/span>Thymus<\/h3>\n<p>\nThe thymus, located in the back of the neck, produces T cells, an essential component of the immune system that seeks out and kills disease-carrying cells. <\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.mometrix.com\/academy\/wp-content\/uploads\/2021\/10\/Thymus.png\" alt=\"&quot;The thymus is labeled on an illustration of the human body &quot;\" width=\"549.99\" height=\"356.076\" class=\"aligncenter size-full wp-image-95227\" style=\"box-shadow: 1.5px 1.5px 3px grey\" srcset=\"https:\/\/www.mometrix.com\/academy\/wp-content\/uploads\/2021\/10\/Thymus.png 970w, https:\/\/www.mometrix.com\/academy\/wp-content\/uploads\/2021\/10\/Thymus-300x194.png 300w, https:\/\/www.mometrix.com\/academy\/wp-content\/uploads\/2021\/10\/Thymus-768x497.png 768w\" sizes=\"(max-width: 970px) 100vw, 970px\" \/><\/p>\n<h3><span id=\"Spleen\" class=\"m-toc-anchor\"><\/span>Spleen<\/h3>\n<p>\nThe spleen, the lymphatic system\u2019s largest organ, is the cleansing mechanism.

But those aren\u2019t the only protections.<\/p>\n<h2><span id=\"General_Immune_System_Defenses\" class=\"m-toc-anchor\"><\/span>General Immune System Defenses<\/h2>\n<p>\nThere are general immune system defenses, too. Even our <strong>skin<\/strong> is part of the immune system because it contains cells that can kill invading bacteria. The <strong>ciliated mucous membrane<\/strong> acts like a Venus fly trap, catching dirt and other particles before they can enter the respiratory system. <\/p>\n<p><strong>Glandular secretions<\/strong> destroy bacteria while gastric secretions, or acids, also destroy pathogens. Even <strong>bacteria<\/strong> itself helps defend the immune system. Normal bacteria populations battle with pathogens in the gut and vagina, acting as a defense against harmful bacteria. White blood cells also play a big part in our immune defenses. <\/p>\n<h2><span id=\"White_Blood_Cells\" class=\"m-toc-anchor\"><\/span>White Blood Cells <\/h2>\n<p>\nThere are five types of white blood cells that can be classified into two broad categories based on their structure: granulocytes and agranulocytes.<\/p>\n<h3><span id=\"Granulocytes\" class=\"m-toc-anchor\"><\/span>Granulocytes<\/h3>\n<p>\nGranulocytes are a category of white blood cells that form in the bone marrow and play a role in fighting disease. There are three types of granulocytes. <strong>Neutrophil<\/strong> is the quick strike team, responding quickly to invaders. <strong>Basophil<\/strong> signals the body during an invasion, and <strong>eosinophil<\/strong> releases a substance that kills the pathogen. <\/p>\n<h3><span id=\"Agranulocytes\" class=\"m-toc-anchor\"><\/span>Agranulocytes<\/h3>\n<p>\nAgranulocytes are also formed in the bone marrow and are given their name because they do not have obvious granules in the cytoplasm. There are two types of agranulocytes: monocytes and lymphocytes.<\/p>\n<h4 style=\"margin-bottom: 0em; font-weight: 600 !important; font-size: 105%\"><span id=\"Lymphocytes\" class=\"m-toc-anchor\"><\/span>Lymphocytes<\/h4>\n<p>\nLymphocytes include B cells, T cells, and natural killer cells (NK cells) and are more common in the lymphatic system than the blood. <\/p>\n<p>B lymphocytes or B cells make antibodies that specifically target bacteria and go on a search and destroy mission.<\/p>\n<p>T lymphocytes, or T cells, are the attack force. They attack and kill infected cells. There are different types of T cells. Helper T cells play a critical role in regulating the immune system&#8217;s response, and they also stimulate B cells to make antibodies.<\/p>\n<p>Killer T cells kill virus and cancer cells, while the memory T cells seem to have a mind of their own. That\u2019s because memory T cells learn from their past encounters with infected cells and remember how to defeat them. And then, suppressor T cells stop the immune system&#8217;s response after pathogens no longer pose a threat.<\/p>\n<p>The last lymphocyte is the natural killer cells, which bind to certain cells infected with cancer and viruses and kill them. The natural killer cells identify cells that cannot be detected by the T cells.<\/p>\n<h4 style=\"margin-bottom: 0em; font-weight: 600 !important; font-size: 105%\"><span id=\"Monocytes\" class=\"m-toc-anchor\"><\/span>Monocytes<\/h4>\n<p>\nMonocytes, the other type of agranulocyte, are the largest and longest-living phagocyte, cells that act like Pac-Man and eat bacteria and other pathogens. Located in the lymph, monocytes also alert T cells to the presence of those bacterial invaders. Monocytes eventually leave the bloodstream and become macrophages attacking microorganisms and removing dead cell debris.<\/p>\n<p>White blood cells are also called <strong>leukocytes<\/strong>, which are produced in red bone marrow, the home of red blood cells, platelets, and white blood cells. <\/p>\n<h2><span id=\"Antigens_and_Antibodies\" class=\"m-toc-anchor\"><\/span>Antigens and Antibodies<\/h2>\n<p>\nLet\u2019s talk about antigens and antibodies and what happens when they enter our bloodstream.<\/p>\n<p>An invader that enters our body, typically as a protein from bacteria, viruses, or fungi, is called an <strong>antigen<\/strong>. When these antigens invade, the antibody-mediated response kicks in and repels the invader. <strong>Antibodies<\/strong> are part of the response. They can recognize antigens and counteract them.<\/p>\n<p>We\u2019ve already gone over quite a bit of information, so let\u2019s do a short review of the immune system\u2019s steps.<\/p>\n<h2><span id=\"Immune_System_Process\" class=\"m-toc-anchor\"><\/span>Immune System Process<\/h2>\n<p>\nThere are five steps we\u2019ll look at. <\/p>\n<p>It all starts with macrophages, which engulf antigens and break them down. <\/p>\n<p>Next, a helper T cell joins the macrophages. <\/p>\n<p>Then the body activates killer T cells and B cells, and it\u2019s at that point that the killer T cells go on their search and destroy mission. These killer cells look for and kill cells with the same antigen.<\/p>\n<p>B cells then morph into plasma cells and memory cells.<\/p>\n<p>The immune system contains two separate parts: the innate immune system, for general defense, and the adaptive, for more specific defense. <\/p>\n<h3><span id=\"The_Innate_System\" class=\"m-toc-anchor\"><\/span>The Innate System<\/h3>\n<p>\nWe\u2019re all born with an immune system that includes skin, mucus, and even earwax. That\u2019s the innate system, which springs into action like a first-strike force, quickly attacking pathogens that have invaded our body. Here\u2019s an example. You cut yourself, opening a wound that can attract bacteria. The innate system attacks and slows the bacteria.<\/p>\n<h3><span id=\"The_Adaptive_System\" class=\"m-toc-anchor\"><\/span>The Adaptive System<\/h3>\n<p>\nThe adaptive immune system is more selective, attacking specific antigens by zeroing in on the intruders. We noted earlier that Memory T Cells remember how to attack these invaders, and these cells are a part of the adaptive immune system. Put another way, the adaptive immune system has a react and prevent mode. It reacts by killing invaders, but it also prevents disease because of the antibodies\u2019 production of B cells.<\/p>\n<h2><span id=\"Natural_and_Artificial_Immunity\" class=\"m-toc-anchor\"><\/span>Natural and Artificial Immunity<\/h2>\n<p>\nBut how does the body fight against pathogens? There are several ways, both naturally and artificially. <\/p>\n<p>Natural forms of immunity come directly from our own bodies, while artificial forms come from vaccinations. Let\u2019s take a closer look. <\/p>\n<h3><span id=\"Naturally_Acquired_Active_Immunity\" class=\"m-toc-anchor\"><\/span>Naturally Acquired Active Immunity<\/h3>\n<p>\nThe body has a natural active and passive immunity. Let\u2019s take a look at naturally acquired active immunity. When the body becomes infected with a pathogen, it gets the disease. But our body kicks into gear with an immune response that neutralizes the pathogen. Think of it as being exposed to an invader without an immunization. <\/p>\n<h3><span id=\"Naturally_Acquired_Passive_Immunity\" class=\"m-toc-anchor\"><\/span>Naturally Acquired Passive Immunity<\/h3>\n<p>\nThe body also has a naturally acquired passive immunity that happens during pregnancy, when antibodies go from the mother to child, protecting the newborn through childhood.<\/p>\n<h3><span id=\"Artificially_Acquired_Active_Immunity\" class=\"m-toc-anchor\"><\/span>Artificially Acquired Active Immunity<\/h3>\n<p>\nThen there are artificial means of building immunity. You know all those vaccinations you get as a child? That\u2019s a way of building artificially acquired active immunity. <\/p>\n<h3><span id=\"Artificially_Acquired_Passive_Immunity\" class=\"m-toc-anchor\"><\/span>Artificially Acquired Passive Immunity<\/h3>\n<p>\nOn the other hand, artificially acquired passive immunity is from antibodies that come from another individual or animal. These immunizations provide quick protection during an outbreak or emergency.<\/p>\n<p>So that\u2019s our overview of the immune systems, the fighters within us that ward off disease and keep us healthy.<\/p>\n<p>See you guys next time!<\/p>\n<ul class=\"citelist\">\n<li><a href=\"http:\/\/www.cancerindex.org\/medterm\/medtm9.htm\"target=\"_blank\">Cotterill, Simon. \u201cLymphatic System and Immune System | Medical Terminology for Cancer.\u201d Cancerindex.org<\/a><\/li>\n<li><a href=\"http:\/\/www.lymphnotes.com\/article.php\/id\/151\/\"target=\"_blank\">\u201cThe Lymphatic System.\u201d Lymphnotes.com<\/a><\/li>\n<li><a href=\"http:\/\/natamcancer.org\/lymphedema-intro.html\"target=\"_blank\">\u201cHome | Native American Cancer Initiatives, Inc.
